As I recall, you have to buy the luxury package in order to get the nav system. So that's $2,190 for the luxury package and $2,495 for the navigation system, a total of $4,685 or more than a ten percent bump in the price. Sales tax will be higher, of course, and since licence fees and insurance are based on purchase price, they'll be higher too. All that so you don't have to buy a $6.95 map. Not for me. I didn't buy either the lux or nav packages.
